Ski socks. I think the size is about 16cm. Please check the photo of the measurement with a ruler in the third photo. There is some wear and tear, but I think there is no problem with wearing them. Please check the condition in the photos. Home cleaned. I remember buying them at Sports Depot. Please note that this is a personal inspection and the item is being sold at a low price, so no claims are accepted. Please also check my profile.
